Abstract: A carton, e.g., a straight tuck style or sealable end style, intended to minimize pilferage, particularly at the retail outlet, of the product, contained therein. The carton includes a window opening which is enclosed by a transparent heat-shrinkable membrane having peripheral segments thereof secured to predetermined portions of the sidewalls, the dust flaps, and the closure flaps. The carton may optionally include shelf structure for supporting the product. The membrane structure restrains the product in an optimum orientation subsequent to the membrane being shrunk. The dust flaps define in part prominent spaces at either end of the carton which assure that the membrane is not pinched when assembling the carton, therefore, the membrane is free to totally pull away from the window as it is shrunk. Blanks for producing the above-described cartons are also disclosed herewith.
